@Cpt_Kirk pretty much nailed what I was going to say.
By biggest gripes are, or rather what I'll second is:
1.) the trim is crazy sensitive and jumpy. No slow gentle tweaking like on Pipers and Cessnas. I hand flew for initial climb and most of the descent but for cruise used autopilot because it was far easier
2.) watch the CHTs, at least around here we had to do a lot 500 fpm climbs keeping the airspeed up to keep the temps cool
3.) the brakes and taxiing are weird
4.) you will hate traveling in anything else
5.) the sidestick actually feels more natural to me now. For cost reasons I'm flying a 172 recently, but it doesn't feel as natural as the sidestick despite getting all my original training on Warriors and Skyhawks. Somehow the yoke feels two dimensional where the sidestick gave me the illusion of infinite range of motion
*to me it felt like I went from a beat up elderly car that had to be coaxed along and into a brand new BMW 3. The only thing that makes transition "back" down to a 172 easier is that at least around here they rent for 1/2 or even 1/3 the rate... so there's that!
**the training syllabus is great though, nice that a manufacturer gives such specific lesson plans, etc. and it comprehensively covers all key components of the plane. It felt much more "legit" than the other fixed gear checkouts I'd had in other planes where it's pretty much "use the checklist and don't be stupid"
Now my favorite things: it's fast, it's comfortable, it feels safe, rides turbulence better (it feels less floaty if that makes sense). Launching out on a 300nm cross country the Cirrus will win every time for me over a 172 or Archer, hands down
